SC1578 converter equivalent, high-efficiency step-down dc-dc converter.
* 4V to 24V input voltage operation.
* High efficiency (up to 95%).
* Low quiescent current at 90µA.
* Pulse-skipping and pulse-frequency modulation.
.
* Notebook 5V/3.3V main power
* Step-down DC-DC converter module.
* Constant current source for battery char.
The SC1578 is a high performance step-down DC-DC converter, designed to drive an external P-channel MOSFET to generate programmable output voltages. Two main schemes of pulse-skipping and pulsefrequency modulation are employed to maintain low quiesce.
